The Science Geek Extravaganza Advent Calendar

Roy Doty designed this Rube Goldberg Christmas card in which Santa wishes you a Merry Christmas in the most inefficient way possible. It's today's treat from the Science Geek Extravaganza Advent Calendar at Science Creative Quarterly, now in its fifth day.

Day four looks into the possibility that the G protein-coupled receptor agtrl1b is responsible for the Grinch's heart being three sizes too small.

Day three proposes the theory that Rudolph's red nose was due to a parasitic infection of his respiratory system.

Day two presents vintage biodiversity images with a Christmas twist.

Day one shows us the Christmas Tree Cluster near the Cone Nebula, or NGC 2264. That's a picture from space.
